This volume develops original methods of analyzing biased technological progress in the theory and empirics of economic growth and income distribution. Motivated by sharp increases in wage and income inequalities in the world since the beginning of the new century, many macroeconomists have begun to realize the importance of biased technological changes. However, the comprehensive explanations have not yet appeared. This volume analyzes the effects of factor-biased technological progress on growth and income distribution and shows that long-run trends of the capital-income ratio and capital share of income consistent with Piketty’s 2014 empirical results emerge. Incorporating the modified version of induced innovation theory into the standard neoclassical growth model, it also explains the long-run fluctuations of growth and income distribution consistent with the data shown in Piketty. Introducing a wage-setting function, the neoclassical growth model is modified to account for unemployment as well as to examine the dynamics of unemployment and the labor share of income under biased technological progress. Applying a new econometric method to Japanese industrial data, the authors test the key assumptions employed and important results derived in the theoretical part of this book.

This unique volume consists of studies on medium-run macroeconomics that deal with aggregate economic issues that do not easily fit into either short-run business cycles or long-term growth. This research area has emerged over last decade as a new and distinct field, and needs further explorations.The book includes theoretical as well as empirical studies that cover topics related to medium-run phenomena, such as ‘growth and fluctuations’, ‘wages and unemployment’, ‘financial instabilities’, ‘ firm size distributions and unbalanced growth’, ‘income inequality’, etc.. Every chapter includes new approach or new findings and will be invaluable to developments in this emerging area of research.

This book clarifies the mechanism of widening income inequality and declining labor share in macroeconomics, growth, technology, and the labor market, and provides policy implications. The volume covers three research themes: the influence of structural change, the advancement of artificial intelligence, and the phenomena of market concentration on inequalities and labor share dynamics in theory and empirics. The wide array of theoretical topics in this book includes the implications of unbalanced growth, economy-wide elasticity of substitution between capital and labor, relatively rising service sectors, superstar firm phenomena, automation, the heterogeneity of capital, increasing returns to scale, and the information and financial service sectors on inequalities and labor share decline. These analyses are based on multifactor, multisector general equilibrium, the goods market, and the labor market’s imperfectly competitive framework. In addition, the book covers the relevant empirical data analyses that involve top wealth dynamics in the U.S. Forbes 400, the effect of deepening ICT capital on the labor share in major Japanese industries, and the emergence of increasing returns to scale in the Japanese information and financial sectors.
